09c6ac095a Adapting the configuration files: gnss-sdr.conf and gnss-sdr_gn3s_realtime.conf to the new features of the receiver (now, the calculation of acquisition threshold is made from the probability of false alarm).

0bf9e44eb4 SUPL assistance support in progress: 
- New SUPL parameters available in GNSS-SDR.conf
- Ephemeris assistance for real-time operation is now functional
- SUPL client now stores the received ephemeris in XML file. This file can be loaded on request to enable post-processing SUPL assistance and to enable SUPL assistance without internet connection. -> thowards a complete warm start GNSS-SDR.

BUG FIXES:
- GN3S driver firmware file copy operation in CmakeLists.txt had an error that mismatches the gn3s_firmware.ihx file location and prevents the correct firmware loading for GN3S SiGe USB dongles.

8b2d21c1c9 Major changes: 
- Gps telemetry decoder and PVT now uses independent queues for ephemeris, iono, utc_model and almanac. The old gps_navigation_queue is now deprecated and it is removed from the implementation. This affect almost all the PVT and Rinex printer classes.
- Rinex printer class updated to use the new ephemeris, iono, utc_model objects
Bug fixes and correction:
- The pseudorange generation now is based on the computed TOW for each received symbol. The History_Shift computation become simplier in this way. This modification is also a solution for a bug where the pseudoranges became temporally invalid when the TOW is updated (that happen every 6 secons!)

9d34147e0f Major update to improve the GNSS-SDR pseudorange precision and correct some PVT bugs: 
- Updated all available trackings to generate the tracking_timestamp_secs taking into account the remainder code phase.
- Updated the telemetry decoder to track the number of symbol shifted from the preamble start symbol (to be used in observables).
- Updated observables to align the reference channel symbol with the corresponding symbols in the other channels and compute pseudorranges using the common transmission time algorithm.
- Updated PVT to independize the display output rate from the RINEX and KML log files. New options available in config file!
- Some minor improvements and code cleaning.
